  • Upgrade firmware Mikrotik

    This is step by step to upgrade firmware mikrotik

    Upgrade process

    • First step - visit www.mikrotik.com and head to the download page, there choose the type of system you have the RouterOS installed on.
    • Download the Combined package, it will include all the functionality of RouterOS:

    Using Winbox

    Choose your system type, and download the upgrade package:
    Downloadpage.jpg
    Connect to your router with Winbox, Select the downloaded file with your mouse, and drag it to the Files menu. If there are some files already present, make sure to put the package in the root menu, not inside the hotspot folder!:
    Winbox1.jpg
    The upload will start:
    Winb2.jpg
    After it finishes - REBOOT and that's all! The New version number will be seen in the Winbox Title and in the Packages menu

    Using FTP

    • Open your favourite FTP program (in this case it is Filezilla), select the package and upload it to your router (demo2.mt.lv is the address of my router in this example). note that in the image I'm uploading many packages, but in your case - you will have one file that contains them all

    Up4.jpg

    • if you wish, you can check if the file is successfully transferred onto the router (optional):

    [normis@Demo_v2.9] > file print
     # NAME                   TYPE                  SIZE       CREATION-TIME
     0 supout.rif             .rif file             285942     nov/24/2005 15:21:54
     1 dhcp-2.9.8.npk         package               138846     nov/29/2005 09:55:42
     2 ppp-2.9.8.npk          package               328636     nov/29/2005 09:55:43
     3 advanced-tools-2.9.... package               142820     nov/29/2005 09:55:42
     4 web-proxy-2.9.8.npk    package               377837     nov/29/2005 09:55:43
     5 wireless-2.9.8.npk     package               534052     nov/29/2005 09:55:43
     6 routerboard-2.9.8.npk  package               192628     nov/29/2005 09:55:45
     7 system-2.9.8.npk       package               5826498    nov/29/2005 09:55:54
    
    • and reboot your router for the upgrade process to begin:
    [normis@Demo_v2.9] > system reboot
    Reboot, yes? [y/N]: y
    
    • after the reboot, your router will be up to date, you can check it in this menu:
    /system package print
    
    • if your router did not upgrade correctly, make sure you check the log
    /log print without-paging
    

    RouterOS massive auto-upgrade

    You can upgrade multiple MikroTik routers within few clicks. Let's have a look on simple network with 3 routers (the same method works on networks with infinite numbers of routers),
    Dude1.png

    RouterOS auto-upgrade

    Sub-menu: /system package update
    RouterOS version 6 has new auto upgrade option. RouterOS checks amazon servers for information if new version is available and upgrades after upgrade command is executed.

    You can automatize upgrade process by running script in scheduler:
    /system package update
    check-for-updates
    :delay 1s;
    :if ( [get current-version] != [get latest-version]) do={ upgrade }
    

    Older option
    RouterOS can download software packages from a remote MikroTik router.
    • Make one router as network upgrade central point, that will update MikroTik RouterOS on other routers.
    • Upload necessary RouterOS packages to this router (in the example, mipsbe for RB751U and powerpc for RB1100AHx2).
    Dude2.png
    • Add upgrade router (192.168.100.1) information to a router that you want to update (192.168.100.253), required settings IP address/Username/Password
    Dude3.png
    • Click on Refresh to see available packages, download newest packages and reboot the router to finalize the upgrade.
    Dude5.png

    The Dude auto-upgrade

    Dude application can help you to upgrade entire RouterOS network with one click per router.
    • Set type RouterOS and correct password for any device on your Dude map, that you want to upgrade automatically,
    Dude6.png
    • Upload required RouterOS packages to Dude files,
    Dude7.png
    • Upgrade RouterOS version on devices from RouterOS list. Upgrade process is automatic, after click on upgrade (or force upgrade), package will be uploaded and router will be rebooted by the Dude automatically.
    Dude8.png

    The Dude hierarchical upgrade

    For complicated networks, when routers are connected sequentially, the simplest example is 1router-2router-3router connection. You might get an issue, 2router will go to reboot before packages are uploaded to the 3router. The solution is Dude groups, the feature allows to group routers and upgrade all of them by one click!
    Dude13.png
    • Select group and click Upgrade (or Force Upgrade),
    Dude14.png

    License issues

    When upgrading from older versions, there could be issues with your license key. Possible scenarios:
    • When upgrading from RouterOS v2.8 or older, the system might complain about expired upgrade time. To override this, use Netinstall to upgrade. Netinstall will ignore old license restriction and will upgrade
    • When upgrading to RouterOS v4 or newer, the system will ask you to update license to a new format. To do this, ensure your Winbox PC (not the router) has a working internet connection without any restrictions to reach www.mikrotik.com and click "update license" in the license menu.
  • Get User account with DNS-Spoofing

    First What is the DNS ? (wikipedia.org)
    The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the internet or a private network. It associates various information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example, http://www.example.com translates to208.77.188.166.
    What does poisoning the DNS allow us to do ?
    It allows us to redirect the traffic to another website.
    First This is the structure of the network :


    1 , 2 and 3 are computers
    1 is the computer being the gateway (could be a router) (172.128.254.1)
    2 is the target computer (172.128.254.10)
    3 is the attacker using cain 
    Note : IPs are just used for this tutorial and chosen randomly. 
    Our work is on computer number 3 :
    1-After you install cain , open it and go to the sniffer tab
    2-Click on configure and choose your adapter

    3-Enable the sniffer (click on the second icon in the toolbar next to the open icon)
    4-Right click in the empty area and choose scan MAC addresses. We get the results above.
    5-Click on the APR Tab

    6-Click on the + sign in the toolbar to add a new ARP poison routing

    7-choose the gateway which is 172.128.254.1 , in the next list you’ll get the IP of the computer 2 which is 172.128.254.10 and click ok 

    8-now click on the APR-DNS tab

     
    9-click on the + sign 
    10-enter the web address that you want to spoof , (in this case when the user goes to facebook he’ll be redirected to myspace) click on resolve type the web address that you want to redirect the user to it, and click ok, and you’ll get the IP of the web address, then click ok

    you'll get something like this:

    11-now to make this work we have to enable APR poisoning , click on the icon next to the sniffer icon, and everything should work as we expect.
    Now the computer 2 will get the routes poisoned and when the user requests http://www.facebook.comhe will be redirected to http://www.myspace.com .
    Imagine what you can do with this technique.
